I would like to load a number of sequences into my compositing network (I have named each sequence with an iteratable folder name). I don't see a for loop available for this network. Can someone suggest how I might load this sequence?

I would like to inspect the world to object transform of a pair of cameras imported via an alembic file. The cameras are clearly separated. If I jump into a camera to inspect it, the transform tab shows 0 rotation, translation and pivot. I am missing something, as these two cameras are definitely not at the world origin.

Can somebody tell me how I can inspect the true world transform of the camera objects I have imported?

Thanks!

I have a geometry node in my obj network group, and an image network in my img network. The image network contains a file op that loads an image for the current frame using the $F global variable (something like <my directory>/<my prefix>.$F6.png. I would like to add a custom variable to this path so that I can control the source directory. For example: <my directory>/<subdir>$MYVAR/<my prefix>.$F6.png

In my geometry network I am creating a custom SOP in C++. This SOP will pull the rastered data from the image network. I would like this SOP to determine which sub directory the image file rasters (in brief, controlling MYVAR).

Is using a global variable like this the correct approach? If so, how do I set an environment variable from a C++ SOP? I haven't found an API to do so yet.

Thanks!
